One-dimensional spectral analysis of the eddy available potential energy growth over a limited region

Abstract

The paper describes development processes on their energetic basis. A special emphasis is given to the role of the eddy available potential energy, Ae arising out of zonal available potential energy, AZ. The process of energy transition C(AZ Ae) can be estimated in the wave number domain by means of a cospectral function fn(H,T) of the isobaric surface height H and the temperature T. IN cases of baroclinic instability prevalence, the fn(H,T), if determined along a cross-sectional line over a limited region, may help the forecast of a given eddy scale development, relevant for that region.
